Definitions

  • the present invention relates to a motor-vehicle door latch. More particularly this invention concerns such a latch particularly set up to protect child occupants of the vehicle.
  • a motor-vehicle door latch normally has a housing, a pivotal lock fork on the housing engageable with a door bolt and pivotal between a locked position engaged around the bolt and retaining it on the housing and an unlocked position permitting the door bolt to move into and out of the housing, a release pawl engageable with the fork and displaceable between a holding position retaining the fork in the locked position and a freeing position out of engagement with the fork and permitting the fork to move into the unlocked position, and a lever mechanism connected to the release pawl and movable between an actuated position displacing the pawl into the freeing position and an unactuated position with the pawl in the holding position.
  • Inside and outside handles operable from inside and outside the vehicle are connected to the lever mechanism to operate it and unlatch the door.
  • Inside and outside lock element are also connected to this mechanism to prevent at least the outside handle from operating the lever mechanism.
  • Such a mechanism works in either of two ways: It can simply block actuation of the inside handle by putting some element in the movement path. Thus the inside handle cannot be moved at all. Alternately it can decouple the inside handle from the latch mechanism so that, even though the inside handle can be actuated, such actuation will have no effect.
  • the blocking-type child-safety systems are disadvantageous in that they must be able to withstand considerable forces. They must be able, for instance, to withstand the force an adult would exert on the inside door handle if he or she was using it thinking it would work. On the other hand, the decoupling-type child-safety systems often are fairly complicated, requiring that several extra elements be added to the already complicated latch structure.
  • Another object is the provision of such an improved child-safety system for a motor-vehicle door latch which overcomes the above-given disadvantages, that is which is of the decoupling type but still is of very simple and inexpensive construction.
  • a motor-vehicle door latch has according to the invention a housing, a pivotal lock fork on the housing engageable with a door bolt and pivotal between a locked position engaged around the bolt and retaining it on the housing and an unlocked position permitting the door bolt to move into and out of the housing, and a release pawl engageable with the fork and displaceable between a holding position retaining the fork in the locked position and a freeing position out of engagement with the fork and permitting the fork to move into the unlocked position.
  • a lever mechanism connected to the release pawl is movable between an actuated position displacing the release pawl into the freeing position and an unactuated position with the release pawl in the holding position.
  • a child-safety lever having a pair of arms is pivotal between a child-safety position and a normal position.
  • An actuating pawl on the housing engages one of the arms of the child-safety lever and is displaceable between an on position holding the child-safety lever in the child-safety position and an off position with the child-safety lever in the normal position.
  • An inside handle operable from inside the vehicle is permanently connected to an inside latching lever pivoted on the other arm of the child-safety lever and has an end engageable with the mechanism to actuate it only in the normal position of the child-safety lever and operatively unengageable with the mechanism in the child-safety position of the child-safety lever so that in the on position the inside latching lever is operatively unengageable with the mechanism and decouples the mechanism from the inside handle.
  • operatively unengageable means that even though the inside locking lever might be able to physically contact the lever mechanism, it is not able to actuate it sufficiently to unlatch the door.
  • the child-safety lever is pivoted about a primary axis on the housing and is provided on its other arm with a pivot defining a secondary axis on which is mounted the inside latching lever.
  • the inside latching lever is provided offset from the secondary axis and at a location generally coincident with the primary axis in the child-safety position with an attachment.
  • the latch further has according to the invention a link connected between the attachment and the inside handle.
  • the actuating pawl according to this invention can be manually actuatable. It can be accessible through a hole in the door edge by a screwdriver or the like so that it is relatively easy to set with a tool, but not easily reset by someone who does not have this simple tool. Alternately it can be operated by a motor that is connected to the actuating pawl for displacing same between its positions. This motor can be a reversible motor that is part of a power-lock system.
  • FIG. 1 is a largely schematic view illustrating the child-safety latch according to the invention in the latched and unlocked position
  • FIG. 1A is a view like FIG. 1 but showing the latch in the latched and locked position
  • FIG. 1B is a section taken along line IB--IB of FIG. 1A
  • FIG. 2 is a view like FIG. 1 showing the latch in the unlocked position
  • FIG. 3 is a side view showing the child-safety system in the on and off positions
  • FIG. 4 is a view like FIG. 3 showing the child-safety cutout in the off position and the inside locking lever in its actuated position;
  • FIG. 5 is a view like FIG. 3 showing the child-safety cutout in the on position and the inside locking lever in its actuated position.
  • a motor-vehicle door latch As seen in FIGS. 1 and 2 a motor-vehicle door latch according to this invention has a housing 1 that is normally mounted on an edge of a door and that is provided with a fork 2 pivotal about a fork axis 2A to engage around and trap a bolt 16 mounted on the unillustrated door post.
  • a pawl 3 pivotal about an axis 3A on the housing 1 can retain the fork 2 in the locked position of FIG. 1.
  • a two-lever mechanism 5 pivotal about axes 5A on the housing 1 is operable to pivot the pawl 3 into the freeing position of FIG. 2 and release the bolt 16. This structure is all standard.
  • the lever system 5 is formed of levers 5a, 5b, 5d, and 5e and a link 5c pivoted on the housing 1 or on each other at axes 5A', 5A", 5A'", and 5A"".
  • Lever 5a is pivoted at 5A'" on the housing and is formed with a radially extending slot 5a' which serves as a guide for pins 5c' and 5e" described below.
  • the sole function of the lever 5a is to guide the pins 5c' and 5e' and couple them together so that when the one pin 5e', for example, moves, the other pin 5c' will follow his movement.
  • the lever 5b is pivoted on the axis 5A'" between the lever 5a and the housing 1 and has a tooth 5b' that can engage a pin 3' on he release pawl 3 and a tab 5b" that can be engaged by the pin 5c'.
  • the pin 3' projects through a slot 1a in the housing 1.
  • the link 5c has a lower end in which is fixed the lower pin 5c' that rides in the slot 5a' and that can engage the tab 5b".
  • the upper end of the link 5c is pivoted at 5A" on the outer end of the lever 5d which is pivoted at 5A' on the housing 1.
  • This lever 5d is shown in FIG. 1A in he locked position in which its left-hand end is raised and right-hand end is lowered so that the link 5c is lowered and the pin 5c' is below the tab 5b". It can be pivoted somewhat counterclockwise from this position to the position of FIG. 1 to unlock (not unlatch) the door into a position with the pin 5c' raised and engageable with the tab 5b".
  • the lever 5e is L-shaped and is pivoted at 5A"" on the housing 1. It has an upper arm operable by an inside door handle lever 4 and a lower arm provided with the upper pin 5e' riding in the slot 5a' above the pin 5c'.
  • the lever 5e is pivoted clockwise about the axis 5A"".
  • the pin 5e' couples the 1ever 5a to the lever 5e for joint pivoting, albeit about different axes in different directions, so that this movement will also push the other pin 5c' in the slot 5a' toward the left. If the pin 5c' is in the lower locked position of FIG.
  • a child-safety system 6 carried on the housing 1 comprises a two-arm lever 7 pivoted centrally at an axis 8, a biasing spring 9, and an actuating pawl 10.
  • the pawl 10 can pivot between the solid-line on position of FIGS. 3 and 5 and the dot-dash off position of FIG. 3 to correspondingly pivot the lever 7 between respective similarly illustrated child-safety and normal positions.
  • the spring 9 urges the lever 7 continuously into the normal position.
  • the lever 7 is provided with a pivot 17 defining a secondary axis and carrying an L-shaped two-arm latching lever 4.
  • One arm of this lever 4 is provided with an attachment 11 connected via a bowden cable 12 or rod to an inside door handle 18 and another arm 14 can act on the lever mechanism 5 to unlatch the door.
  • the pawl 10 which may be operated by an electric motor shown schematically at 20 in FIG. 5, is in the on position and the child-safety lever 7 is pulled back to its child-safety position and the inside latching lever 4 cannot actuate the lever 5. Even if pulled back by the handle 18, the lever 4 is positioned so that it cannot move the lever mechanism 5 enough to release the pawl 3 from the fork 2. Thus operation of the inside handle 18 will not unlatch the door.
  • the attachment location 11 of the inside-handle link 12 is directly aligned in the unactuated position of the lever 4 with the pivot 8 of the lever 7 so that displacement of the lever 7 between its positions will not change the position of this attachment 11, thereby having no effect on the linkage 12.
